Hello, I’m pretty new to the pumping world as I recently shut down a masonry company due to the national tragedy that folks in Alabama call lazy people that don’t want to work. Anyway I decided since I had a pump already I’d do it full time for the public and I enjoy it. That being said I have a 2020 Putzmeister tk40 that refuses the grease. I have tried air grease guns, electric, and manual guns and nothing will work. I know there’s a blockage so my question is this: where should I look first? I’m sure you all know how it works having the one fitting going into a grease block then out to its several destinations! I’ve actually took lines off at certain areas to check for grease pressure only to find there isn’t any. So do I chase the problem starting at the entry side of the block or what? I mean it’s flipping grease, how do you plug up a grease line? Surely it’s gonna be some dried cement in the way at a grease point but then why is it not greasing anywhere else? Anything would suffice guys. Thanks in advance  for the help.

Thanks for the video link. I feel dumb for even asking the question. Now I know what I need to look at and check for lubricant. Thanks again! 

if you ask you are just a moment dumb, a wise old men told me.

my biggest problem was marine grease cuz it would cake up. so on a hot day with a electric gun and a locker tip i could blow some of the build up clear. other wise i have pulled the back end off and cleaned it without replacing much once i was in there.

Lock N Lube grease gun tips really help push out a blocked grease issue 

Troubleshooting Grease System on 2020 Putzmeister TK40

Based on your description of a complete grease system blockage, here's a systematic approach to resolve this issue:

Where to Look First

1. Start at the Main Grease Distributor Block

   • This is the central component where grease enters before being distributed
   • Check if the small pin on the round plug moves in and out when attempting to grease
   • A completely stuck distributor will prevent grease flow to all points

2. Check for Hardened Grease

   • Marine grease can cake up in lines, especially in cooler weather
   • As one community member mentioned, on a hot day with an electric gun and a "locker tip," you might be able to blow through some buildup

3. Try a Lock N Lube Grease Gun Tip

   • Multiple users have recommended these specialized tips for pushing through blocked grease lines
   • They create a better seal and allow more pressure to clear blockages

Step-by-Step Approach

1. Remove the grease fitting from the main distributor block
2. Clean it thoroughly and check for hardened grease or concrete
3. Inspect each individual line from the block for blockages
4. On a warm day, try using an electric grease gun with a Lock N Lube tip for maximum pressure
5. As a last resort, you may need to disassemble parts of the system to clean internally

Remember that even a single plugged grease point can jam the entire distributor, preventing grease flow to all points. Regular greasing at the end of each work day helps prevent these issues.
